BOBBIN.

SPECIFICATION forming part of Letters Patent N0. 768,727, dated August 30, 1904. Application tiled December 16,1902l Serial No. 135,448. (No model.)

To @ZZ whom, it '7n/ty concern.'

Be it known that I, VICTOR BLANGER, of Seaview, in the town of Marshfield, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Bobbin's, of which the following' is a specilicati'on.

This invention has relation to bobbins; and it has for its object to provide certain improvements therein by means of which the tendency to break the yarn when the bobbins are initially rotated is greatly reduced.

In addition the invention has for its object to lighten the operation of doiiing, whereby the frames may be doffed more expeditiously than heretofore.

The invention has further for its object to provide certain improvements in bobbins for rendering them more eiiicient in the spinning operation, as will be understood from the following specification.

Referring' to the accompanying drawings, Figure l represents a spindle having an improved bobbin thereon,the bobbin being illustrated in section. Fig. 2 represents a section on thc line 2 2 of Fig. l.

On the drawings, er indicates the spindle, which may be made in the usual way. The blade is tapered from bottom toward the top and is adapted to be rotated by the whirl The upper end of the blade is rounded, as at d.

The bobbin is indicated as a whole at c. Its exterior surface is substantially cylindrical, except that it is provided with the slightlyenlarged lower portion d. The bore of the bobbin c2 is slightly tapering, although of a diameter slightly greater than the diameter of the blade, so that there is an annular space between the blade and the interior wall of the bobbin, as illustrated in Fig. 2, which is on an enlarged scale and in which the space is shown as more exaggerated. The upper end of the bobbin is closed by the transverse diaphragm or wall c3, which is hollowed out somewhat at c", so as to rest upon the top of the blade. In the upper extremity of the bobbin there is formed an aperture cf' toY permit it to be placed in a shuttle. By reason of this construction the bobbin is supported loosely on itstop upon the extremity of the spindle, its lower end being loose with relation to the spindle. A bobbin constructed in this manner adapts itself to the ring and r'otates with a smoothness that is most desirable in the spinning operation. Inasmuch as it is not in rigid engagement with ythe spindle or a part thereof, its initial rotation does not tend to break the yarn, although after once starting it apparently rotates in unison with the spindle. The bobbin may be dotted with the greatest ease and shows no tendency to rise and leave the spindle, a fault commonly found with bobbins as now constructed.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that'what I claim is- 1. The combination with a rotary spindle, of a wooden bobbin rotated thereby and having an integral diaphragm resting upon the upper end of a spindle, the lower portion of the bobbin being free from engagement with said spindle, whereby the said lower portion is adapted to yield more or less with relation to said spindle.

2. The combination with a rotary spindle, of a wooden bobbin rotated thereby and having a relatively large bore whereby the lower portion of the bobbin is out of engagement with the spindle, the said bobbin having at its upper end an integral diaphragm which rests upon the upper portion of the spindle, said bobbin having in said upper portion an aperture whereby it may be placed in a loomshuttle.

In testimony whereof I have aflixed my signature in presence of two witnesses.
